In this work, we fabricated a biaxially stretchable light-emitting diode (LED) display based on wavy structured-metal electrode grid packaged together with LED chips. The micro-electromechanical systems (MEMS) fabrication process was utilized to fabricate the wavy-structured metal connections and rigid islands. resulting can be readily bent, rolled, stretched even washed no degradation of its i...

This paper presents a new generation of compliant piezoelectric microconveyers for microobjects based on the cooperation of arrayed direct-drive standing wave ultrasonic actuators. A method using an equivalent electromechanical circuit is proposed for estimating and analysing the optimum driving force. On the basis of the proposed method, the friction drive optimization of the micro-robot is pe...

We present novel RF switches using micro-electromechanical (MEM) technology. These MEM switches are built on GaAs substrates using GaAs MESFET MMICcompatible processes. The fabricated shunt switches showed an insertion loss of less than 0.2dB and an isolation of greater than 20dB up to 40GHz. The switching speed is 47μS. The broadband MEM switches are promising building blocks for wideband circ...
